Da Silva worked as a waste collector in Penápolis during his twenties and it was not until 2009, at the age of 27, that he became interested in athletics. Upon the suggestion of his wife, he entered a local race held in honor of Saint Francis of Assisi. Although it was his first attempt at competing over long distances, he surprised himself by finishing in third place.

The following year he entered a 10,000 metres track race in Rio de Janeiro and won in a time of 29:39.72 minutes. At the São Paulo Half Marathon Corpore in April 2010 he came third, then he stepped up in distance to make his debut in the full marathon a month later.

In March he ran in his first race in Europe: he was the first non-African finisher at the Lisbon Half Marathon, where he came tenth in a time of 1:04:10 hours. He then travelled to Italy to compete at the Padua Marathon and he ran a personal best of 2:11:32 hours to finish fourth behind Kenya's . Da Silva returned to Brazil and later that year placed fourth nationally in both the 5000 metres and 10,000 m (including a personal best of 14:12.81 minutes in the former event).

His performances in the marathon gained him selection for the Brazilian team at the 2011 Pan American Games. He entered the competition with the fastest time and delivered on this by winning the gold medal in a time of 2:16:37 hours, having over half a minute to spare over runner-up Diego Colorado of Colombia. This made it a fourth consecutive win for Brazil in the men's Pan American marathon, following on from victories by Vanderlei de Lima and Franck de Almeida.
